Product catalog summary
Overview: The C403H Oxygen/Water Vapor Transmission Rate Test System is designed for high precision and efficiency in testing the transmission rates of oxygen and water vapor through high and medium gas barrier materials. It adheres to standards such as ASTM D3985, ASTM F1249, and ISO 15106-2, making it suitable for various industries including food, medicine, and electronics.
Product Features:
  • Dual Testing Modes: Offers OTR/WVTR, OTR, and WVTR modes for comprehensive testing.
  • Coulometric Oxygen Sensor: Features a ppb level sensor with a longer service life and no calibration required.
  • Infrared Moisture Sensor: Patented sensor with a long service life and automatic protection.
  • Accurate Data: Utilizes 360° air circulation and high-precision sensors for stable temperature and humidity monitoring.
  • High Efficiency: Three independent test cells allow simultaneous testing of three samples.
  • Intelligent Operation: Equipped with a 12-inch touch panel and automatic test modes for ease of use.
  • Safety and Reliability: Embedded industrial computer and intelligent sensors ensure safe operation.
  • Powerful Functions: Offers professional test modes and displays various transmission rate curves.
Testing Principle: The system clamps a pre-treated sample between test chambers, with gases flowing on either side. Oxygen or water molecules diffuse through the sample and are measured by sensors to calculate transmission rates.
Reference Standards: Includes ASTM D3985, ASTM F1249, ISO 15106-2, and others.
Test Applications: Suitable for testing films and sheets such as plastic films, composite films, metal foils, and more.
Technical Parameters:
  • OTR Range: 0.01 - 200 cc/(m2·day) for standard area.
  • WVTR Range: 0.005 - 40 g/(m2·day) for standard area.
  • Temperature Range: 15 - 50°C, customizable up to 60°C.
  • Humidity Range: 0% to 90% RH.
Technical Specifications:
  • Test Cell: 3 sets with a standard test area of 50cm².
  • Sample Size: 11.2cm x 11.2cm.
  • Carrier Gas Specification: Requires high purity nitrogen and oxygen.
  • Instrument Dimensions: 60cm x 50cm x 70cm.
  • Power Supply: 120VAC or 220VAC.
Product Configuration: Includes mainframe, tablet, sampler, and optional accessories like a gas purification unit and DataShield system.

Measuring the Impact of Film Thickness on Film Oxygen and Water Vapor Transmission-1

C403H Oxygen/Water Vapor Transmission Rate Test System C403H Oxygen /Water Vapor Transmission Rate Test System is based on the testing principle of Coulometric oxygen sensor and infrared water vapor sensor. It is designed and manufactured according to ASTM D3985、 ASTM F1249,ISO 15106-2 and other relevant standards to provide high precision and high efficiency oxygen and water vapor transmission rate tests for high and medium gas barrier materials. It is suitable for testing the oxygen and water vapor transmission performance of films, sheets and related materials in the fields of food, medicine, medical devices, daily chemicals, photovoltaic, electronic and many others. Product Featuresnote1 OTR/WVTR tested in One Instrument OTR \ WVTR mode, OTR mode and WVTR mode are available for selection. OTR and WVTR tests can be automatically completed for each sample mounting. Genuinely reflect the OTR \ WVTR performance of the same sample, avoiding effect on test data due to sample contamination arising from instrument switching. Coulometric Oxygen Sensor ⚫ ⚫ ⚫ ⚫ The instrument is equipped with a ppb level Coulometric Oxygen Sensor, as one of new Labthink technical achievements, which can obtain a lower limit of the test. Designed according to ASTM D3985 with absolute value, and no calibration is permitted. Longer service life, two times longer than that of a traditional Coulometric oxygen sensor. Over limit alarm and automatic protection. Infrared Moisture Sensor ⚫ ⚫ ⚫ ⚫ The instrument is equipped with Labthink patented infrared moisture sensor which can obtain a lower limit of the test. Designed according to ASTM F1249. Longer service life, non-consumable. Over limit alarm and automatic protection. Using 360 °air circulation constant temperature technology, the temperature stability is better. Equipped with high-precision temperature and humidity sensor, to monitor and record temperature and hu

In the test process, the automatic control on flow, temperature and relative humidity is realized, reaching higher accuracy. Higher test repeatability of 0.01 cc / (m2·day) can be achieved. High Efficiency Three-cell ⚫ Independent three sets of 50cm2 standard area test cells, in line with parallel sample detection required by standards. Three samples can be tested at the same time under the same conditions, with independent tests data. In the same test cycle, the number of samples completed increases from 2 to 3. Automatic sample clamping, saving time and effort, ensuring consistent clamping...

relative humidity flows on one side of the film, and the high purity nitrogen flows on the other side; oxygen or water molecules diffuse through the film into high-purity nitrogen on the other side, and are carried to the sensor by the flowing nitrogen. By analyzing the oxygen or water vapor concentration measured by the sensor, the oxygen or water vapor transmission rate can be calculated.
